South Korea’s $150B Bet: Can “MASGA” Revive U.S. Shipbuilding and Reset Trade With Trump?

‘MASGA’ Diplomacy: Seoul’s $150B Shipyard Pledge Aims to Rewire U.S.–Korea Trade

South Korea’s pitch—Make America Shipbuilding Great Again—pairs big checks for U.S. yards with tariff relief and energy buys. The bet: help Washington rebuild capacity and tighten the alliance at the same time.

In July, South Korean trade officials arrived in Washington with a simple message—and a sealed box. Inside were bright-red caps stitched with a new slogan: MASGA, short for Make America Shipbuilding Great Again. The props came with real money: a proposal to put $150 billion into reviving U.S. ship manufacturing via yard purchases, workforce training, supply-chain fixes and repair capacity.

Within weeks, the sides inked a broader package: tariff relief and lower car levies tied to investment, plus a commitment from Seoul to buy $100 billion in U.S. energy. Monday’s Oval Office meeting between President Trump and President Lee Jae-myung is expected to push further on tariffs, defense cost-sharing and the role of U.S. forces on the peninsula.

Seoul’s thesis is straightforward: U.S. shipbuilding has atrophied, while China now commands the global order book. South Korea—home to the world’s largest yard and renowned modular techniques—can shorten America’s rebuild with capital and process discipline. Early proof-of-concept: Hanwha Philly Shipyard, acquired last year by Hanwha Ocean, which U.S. Navy leaders said could quickly double headcount and quadruple capacity.

Why shipbuilding—and why now

  • Strategic gap: The U.S. accounts for <1% of commercial output while China approaches 60%. Naval backlogs are mounting as China’s fleet grows.
  • Industrial policy: The White House has floated tax incentives and a shipbuilding office; Congress is weighing a “foreign ally registry” to let trusted partners build and repair more U.S. hulls.
  • Execution help: HD Hyundai says it can deliver a U.S.-spec destroyer at roughly half the domestic cost and in two-thirds the time—knowledge the U.S. wants without offshoring the steel.

What changes if MASGA sticks

  • Faster fixes, closer to the fight: More Indo-Pacific repair capacity frees up U.S. yards for new builds and shortens turnarounds if a crisis flares around Taiwan.
  • Learning-curve transfer: Korean modular build methods and supplier networks can be taught, not imported whole—keeping production onshore but trimming cost and schedule risk.
  • Policy hinges: Progress depends on U.S. rules (Jones Act waivers, ally registry, procurement reforms) that determine how far partners can go.

At a glance

Investor take

Shipbuilding isn’t a straight line. If MASGA moves forward, the beneficiaries are the enablers: U.S. yards that gain backlog, suppliers of propulsion, steel plate, coatings and modular equipment, and Korean firms with U.S. footprints (e.g., Hanwha, HD Hyundai consultancies). Tail risks are policy reversals and slow workforce ramp.

  • Defense contractors / repair yards: Look for repair-capacity awards in the 7th Fleet AOR and public-private yard upgrades.
  • Industrial suppliers: Plate steel, LNG modules, and marine electronics should see early orders.
  • Energy linkage: Seoul’s long-dated U.S. LNG and power deals support Gulf Coast infrastructure names.
